论文摘要
众所周知，Feynman图的对称组可以提供有关其评估策略的重要信息以及将要涉及的数学对象。在量子电动力学中的多环多光子幅度上进行的持续研究的动机，在这里，我将讨论在Feynman-Schwinger参数空间中引入对称性组的多项式基础的有用性。
It is well-known that the symmetry group of a Feynman diagram can give important information on possible strategies for its evaluation, and the mathematical objects that will be involved. Motivated by ongoing work on multi-loop multi-photon amplitudes in quantum electrodynamics, here I will discuss the usefulness of introducing a polynomial basis of invariants of the symmetry group of a diagram in Feynman-Schwinger parameter space.
